Left: Minimum requirement. If the chimney is properly lined with terra-cotta liner tiles with a 6" x 9" opening or smaller, a direct-connect installation is permitted. Remove damper assembly, cut and anchor a stainless steel sealer plate (removable for cleaning) at the throat of the fireplace. Insert a length of 6" stainless flex long enough to reach into the bottom liner tile through a hole cut in the sealer plate.

Advantage: less expensive than full reline

Disadvantages: reduced updraft, increased creosote formation, insert must be removed to clean chimney.

Right: Preferred method, and required for zero-clearance fireplace installations, unlined masonry chimneys, or if existing liner is damaged. Remove damper assembly, install a 6" stainless steel liner the entire length of the chimney, passing through a stainless steel sealer plate at the top of the chimney; finish at top with stainless top clamp, storm collar and rain cap assembly.

Advantages: better updraft, better performance, reduced creosote formation, chimney can be cleaned without removing insert.

Disadvantage: more expensive to install
